GRAVITY FROM THE GROUND UP: An Introductory Guide to Gravity and General Relativity

BERNARD SCHUTZ

Although it has the look and feel of a textbook, this volume is actually a straightforward view of astronomy through the lens of gravity. Schutz' long career has centered on this line of research, and he ably describes gravity's role in the myriad components and events of the universe, ranging from the life cycle of galaxies to the origins of chemical elements. He begins at the surface of Earth and moves outward, explaining how gravity and other physical laws determine the actions of planets, stars, galaxies, and the universe as a whole. Although the text steers clear of advanced mathematics and equations, readers should be armed with a solid background in algebra and trigonometry. Those who want to explore the next level of inquiry are encouraged to download computer programs from a Web site launched in conjunction with the book. These programs help readers find, for instance, the length of a planet's orbit, which would otherwise require the use of advanced calculus.

A glossary and an abundance of images and charts clarify the text. CUP, 2003, 462 p., b&w photos/illus., hardcover, $45.00.
